In the Hospitals of the Ordine della Provincia Romana San Giovanni di Dio Fatebenefratelli (FBF) (consisting of four hospitals located in three Italian regions) Patient Centeredness has always been considered a central point. In 2015, the Central Hospitals' Health Direction decided to use a check-list for the evaluation of the degree of Patient Centered Care Facilities, drawn up by the National Agency for Regional Health Services (Age.Na.S) during the 2010 Research Project "Experimentation and transfer of organizational empowerment models for evaluating and improving the quality of health services." The aim of the work was to measure the "Patient Centered Care degree" of the FBF structures by means of the Age.Na.S. check-list in order to identify effective and sustainable improvement measures, and to evaluate the applicability and the critical points of the questionnaire. The check-list was divided into four areas: care systems oriented at citizen's respect and centrality; physical accessibility, liveability and comfort of the places of care; access to information, simplification and transparency; care of the relationship with the patient and the citizen. The four areas were divided into 12 sub-areas, 29 criteria and 144 items with sub-items (248 questions), defined as quantitative or qualitative variables allowing for an evaluation of observed reality. Some items from different areas have been grouped into Focus and Operational Units (UU.OO./Facilities). The results of the Age.Na.S. study were used to compare the results obtained in the Roman Province FBF structures with the national ones. The Medical Directors and the responsible of FBF Quality Systems completed the cheek-list. A working group within the Central Hospitals' Health Direction analysed the data and processed the results, using the same scores provided by Age.Na.S.. The analysis of the results was divided into three levels. Focus and UU.OO./Facilities scores were calculated based on Age.Na.S.

The red flour beetle, Tribolium castaneum Herbst (Coleoptera: Tenebrionidae), is an economically important pest of stored products. As possible alternative to conventional insecticides for its management, plant essential oils have gained interest owing to their effectiveness and eco-friendly features. However, they also show some drawbacks, such as low stability, poor water solubility and diffusion, and limited persistence in the environment. A good strategy to overcome these disadvantages is represented by green nanotechnologies. Herein, we developed a nanoemulsion based on the essential oil from Pimpinella anisum L. (Apiaceae) containing 81.2% of (E)-anethole and evaluated its toxicity on T. castaneum adults and F1 progeny, as well as its morphological and histological impact. The aniseed oil nanoemulsion was characterized by the formation of a semi-solid interphase between oil and water; mean drop size was 198.9 nm, PDI was 0.303, zeta potential was - 25.4 ± 4.47 mV, and conductivity was 0.029 mS/cm. The nanoemulsion showed toxicity on T. castaneum (LC50 = 9.3% v/v), with a significant impact on its progeny. Morphological and histological damages triggered by feeding and exposure to the aniseed nanoemulsion were analyzed by scanning electron microscopy (SEM) and light microscopy. Overall, our findings showed that the development of nanoemulsions allows to improve the stability of P. anisum essential oil enhancing its efficacy against stored grain pests and contributing to reduce the use of harmful synthetic insecticides.

The performance of seedlings is crucial for the survival and persistence of plant populations. Although drought frequently occurs in floodplains and can cause seedling mortality, studies on the effects of drought on seedlings of floodplain grasslands are scarce. We tested the hypotheses that drought reduces aboveground biomass, total biomass, plant height, number of leaves, leaf area and specific leaf area (SLA), and increases root biomass and root-mass fraction (RMF) and that seedlings from species of wet floodplain grasslands are more affected by drought than species of dry grasslands. In a greenhouse study, we exposed seedlings of three confamilial pairs of species (Pimpinella saxifraga, Selinum carvifolia, Veronica teucrium, Veronica maritima, Sanguisorba minor, Sanguisorba officinalis) to increasing drought treatments. Within each plant family, one species is characteristic of wet and one of dry floodplain grasslands, confamilial in order to avoid phylogenetic bias of the results. In accordance with our hypotheses, drought conditions reduced aboveground biomass, total biomass, plant height, number of leaves and leaf area. Contrary to our hypotheses, drought conditions increased SLA and decreased root biomass and RMF of seedlings. Beyond the effects of the families, the results were species-specific (V. maritima being the most sensitive species) and habitat-specific. Species indicative of wet floodplain grasslands appear to be more sensitive to drought than species indicative of dry grasslands. Because of species- and habitat-specific responses to reduced water availability, future drought periods due to climate change may severely affect some species from dry and wet habitats, while others may be unaffected.

In this study, the effect of chitosan film (CF) with different concentrations of anise essential oil AEO (0, 0.5, 1, 1.5 and 2%) on the quality of chicken burger during chilled storage (4 + 1°C) were examined over a period of 12 days. For this purpose, at the first, the physical and mechanical properties of the produced films were studied. Then, the chicken burger was covered with the produced films. Different treatment were analyzed by biochemical properties such as moisture and thiobarbituric acid, bacteriological properties such as total viable counts and total psychrotrophic counts,Pseudomonas aeruginosa,Staphylococcus aureus, andEscherichia coli. The results of this study showed that adding AEO improved the properties of CF, the moisture, solubility, and water vapor permeability decreased in these films. By increasing the concentration of AEO the tensile strength and elasticity of film were increased. CF with AEO, delayed lipid oxidation in chicken burger and improved the chemical properties of chicken burger. Also, microbial spoilage in these samples decreased significantly (p < .05) compared to the control sample. AEO at 2% in all experiments had better results than other treatments (p < .05), and the AEO (1.5% and 2%) had acceptable biochemical, bacteriological attributes up to end of storage, and these treatments could reduce the population of pathogen bacteria below the acceptable level from day 3 until the end of the storage period. Sensory score of the treatment containing AEO at 1.5% was higher than the sensory score of AEO at 2%. Overall, the results of this study showed that the use of CF with AEO as a natural preservative increased the shelf life of meat products. Considering the relatively similar anti-oxidation and antimicrobial effect of AEO at 1.5 and 2% and also economic aspects, optimum dose for AEO could be 1.5% in the film.

The Apiaceae family encompasses aromatic plants of economic importance employed in foodstuffs, beverages, perfumery, pharmaceuticals and cosmetics. Apiaceae are rich sources of essential oils because of the wealth of secretory structures (ducts and vittae) they are endowed with. The Apiaceae essential oils are available on an industrial level because of the wide cultivation and disposability of the bulky material from which they are extracted as well as their relatively cheap price. In the fight against protozoal infections, essential oils may represent new therapeutic options. In the present work, we focused on a panel of nine Apiaceae species (Siler montanum, Sison amomum, Echinophora spinosa, Kundmannia sicula, Crithmum maritimum, Helosciadium nodiflorum, Pimpinella anisum, Heracleum sphondylium and Trachyspermum ammi) and their essential oils as a model for the identification of trypanocidal compounds to be used as alternative/integrative therapies in the treatment of Human African trypanosomiasis (HAT) and as starting material for drug design. The evaluation of inhibitory effects of the Apiaceae essential oils against Trypanosoma brucei showed that some of them (E. spinosa, S. amomum, C. maritimum and H. nodiflorum) were active, with EC50 in the range 2.7-10.7 μg/mL. Most of these oils were selective against T. brucei, except the one from C. maritimum that was highly selective against the BALB/3T3 mammalian cells. Testing nine characteristic individual components (α-pinene, sabinene, α-phellandrene, p-cymene, limonene, β-ocimene, γ-terpinene, terpinolene, and myristicin) of these oils, we showed that some of them had much higher selectivity than the oils themselves. Terpinolene was particularly active with an EC50 value of 0.035 μg/mL (0.26 µM) and a selectivity index (SI) of 180. Four other compounds with EC50 in the range 1.0-6.0 μg/mL (7.4-44 µM) had also good SI: α-pinene (>100), β-ocimene (>91), limonene (>18) and sabinene (>17). In conclusion, these results highlight that the essential oils from the Apiaceae family are a reservoir of substances to be used as leading compounds for the development of natural drugs for the treatment of HAT.

Motor neurons in the spinal cord are found grouped in nuclear structures termed pools, whose position is precisely orchestrated during development. Despite the emerging role of pool organization in the assembly of spinal circuits, little is known about the morphogenetic programs underlying the patterning of motor neuron subtypes. We applied three-dimensional analysis of motor neuron position to reveal the roles and contributions of cell adhesive function by inactivating N-cadherin, catenin, and afadin signaling. Our findings reveal that nuclear organization of motor neurons is dependent on inside-out positioning, orchestrated by N-cadherin, catenin, and afadin activities, controlling cell body layering on the medio-lateral axis. In addition to this lamination-like program, motor neurons undergo a secondary, independent phase of organization. This process results in segregation of motor neurons along the dorso-ventral axis of the spinal cord, does not require N-cadherin or afadin activity, and can proceed even when medio-lateral positioning is perturbed.
